A Microsoft Exchange clustered resource failed to come online. |
Explanation
This alert indicates that an Exchange clustered resource failed to come online.
Event 1003 indicates a failure to bring the specified Microsoft Exchange Server 2007 cluster resource online. This event may occur when one or more of the following conditions are true:
The specified Exchange Server cluster resource depends on another cluster resource which is not online or could not come online.
The specified resource refers to a mailbox or public folder database which may be inconsistent or corrupted.
There may be networking issues which prevent the specified resource from contacting an Active Directory server.
The user account for the specified resource does not have sufficient permissions to bring the resource online.
Event 1019 indicates that the clustered mailbox sever %1 node %2 failed to bring the Exchange cluster resource %3 online. This error may be triggered by multiple causes. Similarly, the method by which you resolve this error varies greatly depending on what triggered this event in your particular Exchange environment.
Event 1026 indicates that the Network Name of the cluster group has not been Kerberos-enabled. By default, Network Name resources are NTLM authentication enabled.
A VirtualServer is comprised of a network name and IP address resource. The Network Name resource has been updated for Windows Server 2003 to enable the use of Kerberos authentication and the creation of a corresponding computer object. By default, Kerberos authentication and the creation of a computer object for the VirtualServer is disabled and NTLM is used for authentication.
